How to Bathe your Pasta Madre | Bagnetto 

Please remember to turn on subtitles :-)
Bagnetto / Bathing your pasta madre is like a reset of acidity. If you have stored your PM in the fridge for a few days or a few weeks, it's important to bathe it before proceeding to continue feeding. If you feel like your PM is too acidic, then give it a bath. However, speaking from my personal experience, if your PM is weak, bathing it too frequently will weaken it.
